Can cats eat chocolate, and why?
Chocolate is toxic to cats and must be avoided completely. Theobromine causes vomiting, tremors, irregular heartbeat and can be fatal.
Cats are obligate carnivores: they must get most of their nutrition from meat and need nutrients such as taurine that only animal products provide. They lack some enzymes for processing plants and carbohydrates, so fruit and veg offer little benefit and can upset their stomach; many cats are also lactose intolerant.
Warning — what to watch for
Theobromine causes vomiting, tremors, irregular heartbeat and can be fatal.
